TURNING PLUG OR VALVE.

SPECIFICATION forming part of Letters Patent `No. 618,631, dated January31, 1899.

Application led February 6,1897. Renewed July 26, 1898. Serial No.686,939. (No model.)

To all whom, it may concern:

Beit known that I, FREDERICK V. WINTERS, a citizen of the United Statesof America, residing at New York city, in the county and State of NewYork, have invented a new and useful Valve for Regulating the Flow ofGas to a Vessel or other Receptacle, of which the following is aspecification.

My invention has relation to improvements in valves; and the object isto provide a device of the kind named and for the purposes intendedwhich will regulate the flow of gas 4to a receptacle or through thevalve, so that the llow may be diminished or increased at the will ordesire of the person or to suit the objects for which the gas is to bedelivered.

In the drawings, Figure l is a view, partly in longitudinal and verticalsection, showing the complete device. Fig. 2 is a view in elevation ofthe valve-stem and valve. Fig. 3 is a detail view of the valve-plug.

A designates the body of the device, made of suitable metal and of suchdimensions as to meet the objects of its use and being preferably ofdouble conical shape in lengthwise direction, as shown, and provided ateach end with threaded caps, whereby it may be connected tocommunicating pipes, as at l l. Through the body A in vertical directionis formed a round hole 2, in which the valvestem and valve are disposed,and' longitudinally through the' body is formed a gasway 3, intersectingthe vertical way or hole 2 and formed at the ends opening into thevertical way daring or conical, as at 4 A. On the lower end of the bodyis formed a threaded extension 5, having a central aperture 6, and overthis threaded extension 5 is fitted a threaded cap 7, having a centralthreaded aperture 8, registering with the aperture 6 in the body of thedevice. In the vertical valve-stem way 2 at the lower portion is fittedand fixed a plug 9, having a gas way vor port transversely through it,as 10, having flaring ends, as shown, which register with the gaswaythrough the body. The plug 9 is formed with a threaded extension 1l atits lower end,which passes through the aperture of the extension on thebody and engages with the threaded aperture in the cap 7. By means ofthe cap the plug is drawn down on its seat in the body and held firmlyand securely. A packing 12 is arranged in the body below the' base ofthe plug to make the connection gas-tight.

B designates the valve-stem, consisting of a metal stem 13, of smallerdiameter than the hole in which it operates and formed at its lower endwith a hollow shell or open end tube 14, constituting the valve, thelower end of which stands normally a short distance above and free fromthe lower edges of the conical openings in the body and plug, asindicated in the drawings, and the wall of the valve intersecting thegas port or way through the body and plug of the valve to provide for aminimum ilow of gas to the burner or heater, and thus maintain a lowllame continuously, if desired.

On the upper face of the body is formed an extension 16, having exteriorscrew-threads, on which a cap C engages and is held. The cap- C consistsof a hollow cap having interior screw-threads and formed on its top witha vertical circular extension 17, formed with a cam edge 18, providedwith a plurality of steps 19 therein, so that a pin 2O projected fromthe valve-stem will engage and ride on the cam edge and engage and lodgein the notches or steps therein and hold the valvestem at the desiredheight, and consequently raise the valve at the lower end of the stem,so as to admit the desired flow of gas. When the stem has been raised toits limit and it is desired to return it to its lowest position, thestem is turned until the pin runs off the cam edge and drops down thestep 2l into normal position. To accomplish this, l arrange a spring 22on the stem between the under face of the cap O and the shoulder 23,formed in the valve-stem.

The operation and use of my regulatingvalve are readily perceived fromthe description of its uses and purposes. The valve is especiallyintended to be interposed' in a gaspipe or gasolene-pipe for conductingthe fluid to a stove-burner or similar outlet used to heat water toproduce steam in. a vessel or nestof pipes to be conducted to a radiatoror boiler. It will be seen that at the lowest position of the valve buta small quantity of gas` will be admitted, and that when the valve israised' to a higher position the llow will be IOG correspondinglyincreased. It is not intended that the valve shall be used to entirelycut off the flow, but to regulate the quantity, so that the How beingturned on at its source it can be regulated and the burning insured atthe burner continuously, whether the quantity emitted be great or small.IE it is intended to entirelystop the fiow, that is done by shutting itoit at the source of entrance to the pipe feeding the valve.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The valve herein described, comprising a body having a Vertical Steinwaythrough it and a longitudinal gas port or way there- FREDERICK V.lVINTERS.
